1. Imbecilla bifurca Cao & Dmitriev View in CoL sp. nov.

( Figs 10 View FIGURE 10 , 25 View FIGURE 25 m–p)

Description. Ground color off white, infused with brown (specimens preserved in ethanol before examination), eyes grey. Head wider than pronotum. ( Figs 25 View FIGURE 25 m–p)

Pygofer lobe ( Fig. 10c View FIGURE 10 ) with dorsal margin angulately emarginate, hind margin truncate; dorsal appendage ( Figs 10c, d View FIGURE 10 ) with additional thin process on dorso-caudal angle, directed ventrad. Subgenital plate ( Figs 10c, f View FIGURE 10 ) with about 3 macrosetae, with peg-like setae from subbase to middle and rigid setae from subbase to apex. Style ( Fig. 10g View FIGURE 10 ) with second extension very long and curved mesad, with setae on preapical lobe and sensory pits basally on middle part. Connective ( Fig. 10h View FIGURE 10 ) with manubrium wide, central lobe convex on apical margin. Aedeagal shaft ( Fig. 10i, j View FIGURE 10 ) slender, curved subbasally; preatrial processes longer and thicker than shaft, apices slightly bifurcated; gonopore terminal on ventral side.

Measurement. Male length 2.50mm, female length 2.75mm.

Material examined. Holotype: ♂, REPUBLIC OF CONGO, Dept. Pool, Iboubikro site, Lesio-Loun Pk, 340m, 03°16.196'S, 015°28.267'E, 25.viii.2008, coll. Braet & Sharkey. GoogleMaps Paratypes: 2♂, same data as holotype except 29.viii.2008 GoogleMaps .

Etymology. The specific epithet is derived from Latin adjective “ bifurcus ” which means forked, referring to the forked preatrial processes.

Diagnosis. This species is very similar to I. debilis Dworakowska, 1970a , but the pygofer dorsal appendage is shorter and has an additional process close to the basal appendage, the aedeagal shaft is curved and the preatrial processes are bifurcated apically.
